Amazing game, I fucking love the tank operations, although you will need over 8 players per team to make that a fun game mode, I still have a feeling that the tanks will be too powerful.
On the note of COD. I liked World at War, and it seemed Treyarch did all they could to patch and fix that game. I just don't understand how they could have failed Black Ops. The poor map design and unrealistic health bug the shit out of me. But I don't play hardcore because it is stupid that a small pistol round can down you. I want a realistic game, not an entirely accurate one.
Believe it or not there is a difference, as there are 5 different levels of simulation in a game's developement.
